I had a prescription for androderm. Those patches were a pain. They fell off in the shower and they make a crunching noise everytime you move. After my script ran out I thought of a way that might get more test out of them- Take a needle or pin and make a few holes through the membrane seperating the test from your skin(don't go all the through the patch though). I believe that "membrane" only allows a certain amount of test through, so if you puncture it, more test could get through-but that is just a theory.
